Shorter Catechism [Baptist] Q7a - Trinity

Q7: How many persons are there in the Godhead?
A: There are three persons in the Godhead: the Father, the Son, and the Holy Spirit; and these three are one God, the same in substance, equal in power and glory.

■2. God is three persons (Father, Son, & Holy Spirit)
•The fact that God is three persons means that each person of the Trinity is distinct from the other two persons. Matt. 3:16-17; 11:27; 17:5; 28:19 | John 1:1-2; 3:35; 5:20; 12:28; 14:26; 15:9; 16:17; 17:1-3, 23-24 | Rom. 8:27 | 1 Cor. 12:4-6 | Heb. 7:25 | 1 John 2:1, 23
◦The Holy Spirit is a distinct person NOT just the power of God: John 14:17, 26; 15:26; 16:7-14 | Acts 5:3; 8:29; 13:2; 15:28; 16:6-7 | 1 Cor. 2:10-11; 12:11 | Rom. 8:16, 26-27 | Eph. 4:4, 30 | Heb. 10:29
■These would not make sense if the Holy Spirit is just the “power of God”: Luke 4:14 | Acts 10:38 | Rom. 15:13 | 1 Cor. 2:4 | 2 Cor. 3:17

■3. Each person is fully God (coequal and coeternal)
•The Father is God
◦Deut. 31:6 | Ps. 89:26 | Isa. 63:16; 64:8| Mal. 2:10 | Matthew 6:9 | John 6:27; 17:1-3 | 1 Cor. 8:6 | 2 Cor. 1:3 | Eph. 1:3 | 1 Peter 1:3
■This is clearly the case and has never been contested.
